This invention relates to a glass cutting device, withspecial referenceto the cutting of plate glass, after it is inspected, inaccordance withthe marking thereon, so that each plate may be used to the bestadvantage after givin due consideration to its quality and its efects.

The traveling table, above which the cutters are mounted, willpreferably be located 1 alongside the carrier which conveys the platespast the inspectors, and the device is 'so arranged that the plates,after they have on examined and marked, may be conveniently transferredto the table, fed beand then returned to the carrier, to be conveyedtothe place. where the .are sorted and packed.

'l he object of-the present invention is to provide atravelingtable andone or more 20 cutters associated therewith and arranged in such amanner that the successive lates 1 may be handled expeditiously an outeconomically as indicated by the inspector. The surface of the travelingtable comprises similar material have one side of the table there isprovided a g e or stop, 30 against which one edge of t e lass is p aced.One or more cutters may provided, each being mounted u' n a transverseshaft aboveflthe table and 0nd the g e, and arranged so that it maeasily an quickly adjusted laterally o the table. If more than onecutter is provided, the are arranged so that any one may be 8. justedindependently or all may be adjusted simultaneously as a unit.

The detailed construction of theinvention, together with its objects andadvantages, will be'more particularly explained in connectionwith theaccompan drawings, fwhich illustrate one embodiment ereo w In thedrawings:- a Figure 1 is a plan view of the invention with parts thereofbroken away.

The cutting device, to which the inven tionrelates, 13 supported by arectangular frame which is constructed with lon tudinal and transverserails suitable for t 9 ur ose. The .traveling table comprises a ban 11of felt or similar material on which the glass plates 12 are laid.Inside of the band 11 is a traveling belt 13 which passes about pulleysor rollers 14 and 15 mounted at opposite ends of} the frame 10. The owerlap of the belt 13 passes over idler rolls l6 and the lower lap of theband 11 passes over idler rolls 17, the rolls 16 and 17 being supportedin depending brackets 18 secured to the frame 10.

- One of the driving rollers or pulleys, as

14, is mounted in are adjustable longitudinally in brackets 20, by meansof screws 21 or the like, to secure the proper tension on the belt 13.One of the rollers, as 15, to which the driving mechanism is-connected,is mounted in aring boxes 22,- and is driven by any suitable means. Thedri mechanism shown in Fig. 1 comprises a t 23 driven from acountershaft 24 which is connected thro h a gear box 25 to a drivingshaft 26. e shaft 26 is driven by a belt 27 from a motor 28.

The traveling table or band 11 ported b rollers 29.journaled in boxes 30at the si es of the frame. These rollers 29 are arranged quite clmely toeach other so that the table will present an to the plates and avoid anyundue strain thereon. A longitudinal age bar or stop 31 is secured abgveone side (I): the tabla; constitute a e' 'nst w '0 one e of the plate splacgdfas it is fed through the cutters. p

In the present embodiment of there are provided ashort cutter shaft 33 and long'cutter shaft 3%, cutter shafts aresupported in an adjusting plate 37 and a bearing plate 38, and the longshafts 34,

ported at the other side of the table in a bearing plate 39.

As shown in Fig. 33 is supported in the plates 37 and 33 by means ofbushings 4:0 and and the long ported by is secured against vvby. a cap42 secured to the end thereof at ll end 0 T 0 permit the longitudinaladjustment of thelonger shafts 34, and 36, the bushing 0 for each of ithaving a set screw or other securing device 45v whereby the shaft may bemoved longitudinally there secured.

operative position the handle 56 will rest against an abutment 57 whichis adjustably secured to the adjusting plate 37. A weight ,58may bemounted onthejend of the handle 56 to secure the proper pressure of thecutter against the glass. A suitable catch 59 may be provided forengaging the handle 56 to retai'n'the same when it is desired to leavethe cutter in inoperative position.

From the foregoing description it will be the invention 35 and 36. These35 and 36 are further sup-' 5, the short cutter shaft ting elements maybe mounted'in the manner indicated and that they may be readily adjustedcrosswise ofthe table, either individually or collectively. Means areprovided for properly measuring the positions ll respectively shafts 34,.35 and 36 are supsimilar bushings. .The shaft 33 longitudinal movementand ar e3 secured to the shaft at the inner f the bushing 40.

arranged that the successive plates may be removed from the carriers asfast as they are cleaned and inspected and may forthwith be fedthroughthe cutting device. This may be done notwithstanding the fact that itmay be necessary to make different adjustments for each plate. As fastas the plates are delivered fromthe cutting table they may be replacedupon the carrier to them is provided with a hub to the desired positionand Each of these longer shafts may conveniently be marked with ameascontinue their course tov the place where uring scale 46 todetermine the desired adthey are sorted and packed.

Each cutter shaft carries a cut- While thevariousmechanismsemployed ting element 47 which may be secured to in carryingout the invention have been the shaft at any desired The adjusting plateeach end on a sleeve 4. This sleeve is threaded on a spindle as which issecured pending portion 50 of the bearing plate 38.
